Based on the provided legal document, the key points are as follows:

1. The Supreme Court has emphasized that bail cannot be granted in sexual assault cases involving minors without thorough scrutiny of the charges and evidence, especially when the allegations are grave and involve serious offences such as gang rape, threats, and recording of the acts for blackmail purposes [p_11][p_12][p_13][p_14][p_15][p_16][p_17].

2. The Court found that the High Court erred in granting bail without adequately considering the gravity and seriousness of the charges, the prima facie evidence, and the potential risk to the victim, including intimidation and trauma post-bail [p_19][p_20][p_21][p_22][p_23][p_24].

3. The evidence, including victim statements, medico-legal reports, and other material, establish a prima facie case of repeated sexual assault, threatening with a firearm, and recording the acts, which are grave offences under the relevant laws [p_11][p_12][p_13].

4. The Court highlighted that the filing of a chargesheet does not automatically preclude bail, but the court must consider the nature of the offence, the evidence, and the likelihood of witness intimidation or tampering. Failure to do so constitutes a serious error [p_12][p_16].

5. The Court expressed concern over the post-bail conduct of the accused, including threatening and intimidating the victim, which underscores the risk of further harm and the need to prevent tampering with evidence or witnesses [p_11][p_51][p_52].

6. The order granting bail was found to be perverse, unreasonable, and contrary to legal principles governing serious offences against minors, necessitating its cancellation and the accused’s surrender to custody [p_11][p_56].

7. The Court reaffirmed that in cases involving sexual offences against minors, especially those with evidence of coercion, intimidation, and recording of acts, bail should be granted only with extreme caution, considering the potential impact on the victim and the integrity of the trial process [p_11][p_12][p_13][p_51].

8. The Court directed the accused to surrender within a specified period and emphasized the importance of expeditious trial proceedings, ensuring that the process is fair, sensitive, and not oppressive [p_56][p_60].

In summary, the Supreme Court underscored the necessity of careful judicial scrutiny in granting bail in serious sexual offence cases against minors, particularly when there is prima facie evidence of heinous acts, intimidation, or threats, and highlighted that errors in such considerations can lead to cancellation of bail orders to uphold justice and victim protection.
